Frontend Mentor - Launch countdown timer solution

This is a solution to the Launch countdown timer challenge on Frontend Mentor. Frontend Mentor challenges help you improve your coding skills by building realistic projects.

Table of contents

Note: Delete this note and update the table of contents based on what sections you keep.

Overview

The challenge

Users should be able to:

  • See hover states for all interactive elements on the page
  • See a live countdown timer that ticks down every second (start the count at 14 days)
  • Bonus: When a number changes, make the card flip from the middle

Screenshot

Add a screenshot of your solution. The easiest way to do this is to use Firefox to view your project, right-click the page and select "Take a Screenshot". You can choose either a full-height screenshot or a cropped one based on how long the page is. If it's very long, it might be best to crop it.

Alternatively, you can use a tool like FireShot to take the screenshot. FireShot has a free option, so you don't need to purchase it.

Then crop/optimize/edit your image however you like, add it to your project, and update the file path in the image above.

Note: Delete this note and the paragraphs above when you add your screenshot. If you prefer not to add a screenshot, feel free to remove this entire section.

My process

Built with

  • Simple HTML
  • Css
  • JavaScript

Note: These are just examples. Delete this note and replace the list above with your own choices
